摘要： 在总体定性分析的基础上，根据边缘连通度、抗噪性能、运算复杂度等典型的边缘检测算法性能标准，利用定量计算结果比较并验证各种边缘特征提取算法的优缺点。采用B样条三次曲线对原始图像进行拟合，显著提高了检测后的图像质量。实验结果表明，该方法可以很好地应用于图像处理领域。

Abstract: Based on whole qualitative analysis, this paper compares and validates merits and demerits of various edge detection algorithms in a quantificational way from several typical judgement standards for edge detection algorithms like edge connectivity, nosie resistence ability, operation complexity. By means of B cubic spline interpolation, it improves the quality of the detected images. Experiental results show that this methods can be well applied in the region of image processing.

Key words: edge detection, edge connectivity, spectrum map, cubic spline interpolation
